I've been successfully able to predict a behavioral variable from DCM parameter estimate with the PEB LOO functions. However, I'm interested in seeing if these connectivity parameter estimates actually perform better than simply using parameter estimates from the VOIs (or a combination of other VOIs), i.e. NOT connectivity estimates. Just applying occam's razor makes sense in this type of analysis, rigth? Is there any straightforward way of doing this in SPM? I would like to follow the procedures as used for the PEB LOO as closely as possible. Any recommendations or pointers would be helpful!
